在网席草的腿上发现了化学感受器髂嵴。它的特征是有一个弯曲的，钝头的刚毛，从侧面看有两种色调的外观。内部的头发包含一个大的偏心定位腔和一个较小的腔在较重的部分壁。活力染色的亚甲蓝制剂和切片材料显示，这些毛由3个双极感觉细胞支配。两个去任何一个刚毛腔，第三个终止于插座。双色调刚毛在腿上的分布与跗骨对蔗糖的敏感性和局部刺激expts的分布精确相关。其中将单根毛发或一组毛发浸入蔗糖溶液中。证明了这些是接触化学感受器。类似类型的毛发在Phormia的喙上发现，以及在其他几种昆虫的跗骨上发现，其中一些已知具有跗骨化学敏感性。
A chemoreceptive sens ilium trichodeum was found on the legs of Phormia regina Meigen. It is characterized by a curved, blunt-tipped seta which has a two-toned appearance when viewed from the side. Internally the hair contains a large eccentrically located cavity and a smaller cavity in the heavier portion of the wall. Vitally stained methylene blue preparations and sectioned material have revealed that these hairs are innervated by 3 bipolar sense cells. Two go to either of the setal cavities, and the 3rd terminates in the socket. The distribution of two-toned setae on the legs correlates precisely with the distribution of tarsal sensitivity to sucrose, and local stimulation expts. in which a single hair or group of hairs were immersed in a sucrose soln. proved that these are contact chemoreceptors. A similar type of hair was found on the proboscis of Phormia as well as on the tarsi of several other species of insects, some of which are known to have tarsal chemosensitivity.
